A metaphorical term used by older perverts to describe underage girls at public places like the mall or playgrounds.

Old man: Damn sonny women didn't have booties like that back in my day.
Kid: what do you mean where. (While munching out on his Cinnabon)
Old man- well young'n, you see that fine piece a ass with the pigtails walk in in to that build a bearworkshop? That's what we like to call babes in toyland!
